DESCRIPTION:Speakers: MANCINA\, Sarah (University of Wisconsin - Madison)\
nIceCube analyses which look for an astrophysical neutrino signal in the s
outhern sky face a large background of atmospheric muons and neutrinos cre
ated in cosmic ray air showers. Selecting for events which start inside th
e detector suppresses not only the downgoing muon background\, but also th
e southern sky atmospheric neutrino background by the energy- and declinat
ion-dependent atmospheric self-veto effect. By using the good pointing res
olution found with muon tracks\, this selection determines a veto region b
efore the starting vertex for each event and calculates the likelihood for
not observing a hit on the IceCube optical modules in the veto region. Th
is starting track event selection has a high astrophysical neutrino purity
above 10 TeV in the southern sky. We will present on the advantages of th
is event selection for neutrino point source searches and diffuse flux sea
rches and provide a first look at the realtime event stream derived from t
he selection.\n\nhttps://indico.desy.de/indico/event/18204/session/17/cont
